I don't know if somebody improved the dibcom driver, but for my experience
the signal strength numbers are not useful, they only go from a small number
or jump to maximum, so don't trust them. I think there where also some
issues with signal strength on some hardware... but I'm not sure about that.
Apart from that signal issues your device seems to work perfectly, could you
submit the patch to the list to add it to current version?
